Abstract: A computing device for a radar sensor for identifying a disruption of the radar sensor through blocking or interference includes at least one interface for receiving radar data from the radar sensor and at least one processing device configured to determine at least one characteristic figure for a range of values in a noise distribution in the radar data, in which at most few and/at most weakly reflecting objects are present, and evaluate the characteristic figure in order to identify a disruption of the radar sensor.

Abstract: A friction lining plate for a wet-running frictional shift element that can rotate in the assembled condition with no preferred rotation direction, with at least one annular disk-like friction surface that serves for frictional engagement, having grooves through which coolant can flow. The grooves form two overlapping groove sets. Each groove of the first groove set extends at a first angle inclined obliquely to the radial direction and backward relative to a first rotation direction. Each groove of the second groove set extends at a second angle inclined obliquely to the radial direction and forward relative to a first rotation direction. Each groove of the second groove set intersects a groove of the first set in such manner that a groove intersection point is located at the inside diameter of the friction surface or a groove intersection point is located at the outside diameter of the friction surface.
